    What is a switch's function in a circuit?

  • to make the current hotter or colder
  • turn on and off the flow of electrical current
  • the pathway that electrical current flows
  • to add more power to the circuit
  • 8. 
    Look at the picture.  Why won't the light bulb light up?

  • The wires from the light bulb are not connected to the battery
  • The switch is not closed to form a complete circuit
  • The wires from the light bulb are not connected to the switch
  • The wires from the battery are not connected to the switch
  • 9.

  • 15. 
    When all parts of the circuit are connected it is a ______ circuit.

  • open
  • closed
  • 16. 
    Will the light bulb in this circuit light and why/why not?

  • yes, because it has two batteries
  • no, because the switch is open
  • yes, because it is in a circuit
